In most cities and counties, permits will be required for the installation of electrical circuits or the construction of exterior surfaces(decks and gazebos). In addition, some communities have adopted residential barrier codes which may require fencing and/or self-closing gates on the property to prevent unsupervised access to a pool (or spa) by children under 5 years of age. Your Hot SpotSpa is equipped with a locking cover that meets the ASTM F1346-91 Standard for Safety Covers and as a result, is usually exemptfrom most barrier requirements. As a general practice, your local Building Department will inform you of any applicable barrierrequirements at the time a permit is obtained for the installation of an electrical circuit. Your Hot Spot Spa Dealer can provideinformation on which permits may be required.

Congratulations on your decision to enjoy the finest spa available...

Welcome to the growing family of Hot Spot! Spa owners.

SAFETY INFORMATIONIMPORTANT SAFETY INSTRUCTIONSREAD AND FOLLOW ALL INSTRUCTIONSAVOIDING THE RISK TO CHILDREN

WARNING:• RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents,

ensure that children cannot use a spa unless they are supervised at all times.• To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.• To reduce the risk of injury, lower water temperatures are recommended for young children. Children are especially sensitive to hot water.

DO:• Make sure you always lock the child resistant locks after using the spa for your children’s safety. Every Hot Spot® Spa is equipped with a

locking cover that meets the ASTM F1346-91 Standard for Safety Covers.• Test the water temperature with your hand before allowing your child to enter the spa to be sure that it’s comfortable. Children are

especially sensitive to hot water.• Remind children that wet surfaces can be very slippery. Make sure that the children are careful when entering or exiting

the spa.

DON’T:• Allow children to climb onto the spa cover.• Allow children to have unsupervised access to the spa.

AVOIDING THE RISK OF ELECTROCUTIONRisk of electrocution

• Connect only to a grounded source.• Do not bury the power cord. A buried power cord may result in death or serious personal injury due to electrocution if direct burial-type

cable is not used, or if improper digging occurs.• A ground terminal (pressure wire connector) is provided on the control box inside the unit to permit connection of a minimum No. 10 AWG

(6mm2) solid copper bonding conductor between this point and any metal equipment, metal water pipe, metal enclosures of electricalequipment, or conduit within five feet (1.5 m) of the unit as needed to comply with local requirements.

WARNING:• To reduce the risk of electrical shock, replace a damaged cord immediately. Failure to do so may result in death or serious personal injury

due to electrocution.• Your spa is provided with a Ground Fault Circuit Interrupter for user and equipment protection. To ensure proper operation of this

important safety device, test according to the following instructions per electrical configuration.Cord-Connected 115 volt, 15 and 20 amp models: The GFCI is located at the end of the power cord. Before each use, with the unitoperating, push the TEST button. The unit should stop operating and the GFCI power indicator will go out. Wait 30 seconds and thenreset the GFCI by pushing the RESET button. The GFCI power indicator will turn on, restoring power to the spa. If the interrupter does notperform in this manner, there may be an electrical malfunction and with it, the possibility of an electric shock. Disconnect the power untilthe problem has been corrected.230 volt, permanently installed or converted models:

• A ground terminal is provided on the terminal block located inside the control box. To reduce the risk of electric shock, connect thisterminal to the grounding terminal of your electrical service or supply panel with a continuous green, insulated copper wire. The wire mustbe equivalent in size to the circuit conductors supplying the equipment. In addition, a bonding terminal (pressure wire connector) isprovided on the outside of the control box for bonding to local ground points. To reduce the risk of electric shock, this connector shouldbe bonded with a No. 10 AWG solid copper wire to any metal ladders, water pipes, or other metal within 5 feet (1.5 m) of the spa tocomply with local requirements. The means of disconnection must be readily accessible, but must be installed at least 5 feet (1.5 m) from the spa.

• Your spa is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.• Your spa uses ground fault circuit interrupters in the electrical subpanel. Before each use of the spa and with the unit operating, push the

Test button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker byswitching it completely off and then completely on. The switch should then stay on. If either of the interrupters does not perform in thismanner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the power until the fault has beenidentified and corrected.

DANGER: RISK OF ELECTRICAL SHOCK• Install at least 5 feet (1.5 m) from all metal surfaces. A spa may be installed within 5 feet of a metal surface if each metal surface is

permanently connected by a minimum No. 10 AWG (6mm2) solid copper conductor attached to the wire ground connector on the terminalbox that is provided for this purpose if in accordance with National Electrical Code ANSI/NMFPA70-1993.

• Do not permit any electrical appliances, such as a light, telephone, radio, or television within 5 feet (1.5 m) of a spa. Failure to maintain asafe distance may result in death or serious personal injury due to electrocution if the appliance should fall into the spa.

DO:• Be sure your spa is connected to the power supply correctly - use a licensed contractor.• Disconnect the spa from the power supply before draining the spa or servicing the electrical components.• Test the Ground Fault Circuit Interrupter(s) before each use.

DON’T:• Use the spa with the equipment compartment door removed.• Place electrical appliances within 5 feet (1.5m) of the spa.• Use an extension cord to connect the spa to its power source. The cord may not be properly grounded and the connection is a shock

hazard. An extension cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage.• Attempt to open the electrical control box. There are no user serviceable parts inside.

RISKS TO AVOIDDANGER: RISK OF INJURY

• To reduce the risk of injury to persons, DO NOT remove suction fittings (filter standpipes) located in the filter compartment. • The suction fittings in the spa are sized to match the specific water flow created by the pump. Should the need arise to replace the

suction fittings, or the pump, be sure that the flow rates are compatible.• There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa.• People with infectious diseases should not use the spa.• Keep any loose articles of clothing, long hair or hanging jewelry away from rotating jets or other moving components.

Increased side effects of medication• The use of drugs, alcohol, or medication before or during spa use may lead to unconsciousness with the possibility of drowning.• Persons using medications should consult a physician before using a spa; some medication may cause a user to become drowsy, while

other medication may affect heart rate, blood pressure, and circulation.• Persons taking medications that induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants should not use the spa.

Health problems affected by spa use• Pregnant women should consult a physician before using spa.• Persons suffering from obesity or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or

diabetes should consult a physician before using spa.

Unclean water• Keep the water clean and sanitized with correct chemical care. The recommended levels for your Hot Spot® Spa are:

Free Available Chlorine (FAC): 3.0-5.0 ppm Total Alkalinity: 125-150 ppmWater pH: 7.4-7.6 Calcium Hardness: 150-200 ppm

(Refer to Water Quality and Maintenance section for complete instructions.)IMPORTANT: Turn on the jet pump for a least ten minutes after adding ANY spa water chemicals into the filter compartment.

• Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limitthe flow, or trip the high limit thermostat which will turn off the entire spa.

AVOIDING THE RISK OF HYPERTHERMIAProlonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the bodyreaches a level above normal (98.6°F or 37°C). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat,failure to recognize the need to exit the spa, physical inability to exit the spa, fetal damage in pregnant women, and unconsciousness resulting in adanger of drowning.

WARNING:The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.

Page 2 Safety Information

Safety Information Page 3

TO REDUCE THE RISK OF INJURY:• The water in the spa should never exceed 104°F (40°C) . Water temperatures between 100°F (38°C) and 104°F (40°C ) are considered safe

for a healthy adult. Lower water temperatures are recommended for extended use (exceeding ten minutes) and for young children.Extended use can cause hyperthermia.

• Pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C). Failure to do so may result in permanent injuryto your baby.

• Do not use spa immediately following strenuous exercise.

AVOIDING THE RISK OF SKIN BURNS:WARNING:

• To reduce the risk of injury, before entering a spa the user should measure the water temperature with an accurate thermometer, since thetolerance of temperature-regulating devices may vary by as much as ±5°F (3°C).

• Test the water with your hand before entering the spa to be sure it’s comfortable.

SAFETY SIGNEach Hot Spot® Spa is shipped with a SAFETY SIGN in the owner’s package. The sign, which is required as a condition of Product Listing, shouldbe permanently installed where it is visible to the users of the spa. To obtain additional SAFETY SIGNS, contact your Hot Spot dealer and requestPart #003021.

IMPORTANT SPA INSTRUCTIONSThe following contains important spa information, and we strongly encourage you to read and apply them.

DO:• Use and lock the cover when the spa is not in use, whether it is empty or full.• Follow the Spa Care and Maintenance recommendations stated in this manual.• Use only approved accessories and recommended spa chemicals and cleaners.

DON’T:• Leave the Hot Spot Spa exposed to the sun without water or the cover in place. Exposure to direct sunlight can cause solar distress of the

shell material.• Roll or slide the spa on its side. This will damage the siding.• Lift or drag the vinyl cover by using the cover lock straps; always lift or carry the cover by using the handles.• Attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the spa owner will

void the warranty. If you have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are notable to resolve the problem, contact your authorized Hot Spot Spa Dealer. Many problems can easily be diagnosed over the telephone byan Authorized Service Technician.

SAVE THESE INSTRUCTIONS

INSTALLATION INSTRUCTIONSSITE PREPARATIONYou probably have a spot picked out for your new spa, whether it’s indoors or outdoors, on a patio or on a deck. Just make sure you check thefollowing:

• Always put your spa on a structurally sound, level surface. A filled spa can weigh a great deal. Make certain that the location you choosecan support the weight of your filled spa.

• Don’t forget to level your spa before filling it (see Spa Leveling Preparation on next page). • Locate your equipment compartment, which houses all of the electrical components, in a place where water will drain away from it.

Allowing water into the equipment compartment can damage the electronics, or may result in tripping your house’s circuit breaker.• Leave yourself easy access to the Ground Fault Circuit Interrupter (GFCI) for testing. The GFCI is located at the end of the power cord, or

at the subpanel of a hard-wired spa.• Never let water get into the subpanel or into the electrical outlet that your spa is plugged into. Consult your local code authority to

determine if an electrical outlet with a cover is required for your installation. • Leave access to the equipment compartment for periodic spa care and maintenance.

WARNING: Damage to the spa’s equipment compartment components or internal plumbing as a result of rodent infestation is NOT

covered under your warranty!

OUTDOOR AND PATIO INSTALLATIONNo matter where you install your new spa, it’s important that you have a solid foundation to support it.Structural damage to the spa, resulting from incorrect installation or placement on an inadequate foundation, isnot covered under the spa’s limited warranty. If you install the spa outdoors, we recommend a reinforced concrete pad at least four inches thick. Thereinforcing rod or mesh in the pad should be attached to a bond wire.

DECK INSTALLATIONTo be certain your deck can support your spa, you must know the deck’s maximum load capacity. Consult aqualified building contractor or structural engineer. To find the weight of your spa, its contents and occupants,refer to the Spa Specifications chart on the back cover. This weight per square foot must not exceed thestructure’s rated capacity, or serious structural damage could result.

INDOOR/BASEMENT INSTALLATIONBe aware of some special requirements if you place your spa indoors. Water will accumulate around the spa, soflooring materials must provide a good grip when wet. Proper drainage is essential to prevent a build-up of wateraround the spa. When building a new room for the spa it is recommended that a floor drain be installed. The humidity will naturally increase withthe spa installed indoors. Water may get into woodwork and produce dry rot, mildew, or other problems. Check for airborne moisture’s effects onexposed wood, paper, etc. in the room. To minimize these effects, it is best to provide plenty of ventilation to the spa area. An architect can help todetermine if more ventilation must be installed. Your spa dealer can help you with local information such as zoning regulations and building codes.

WARNING: Please keep the area around your spa well ventilated when it is installed indoors or in a confined area. Inadequate ventilationaround the spa could cause a build-up of a higher-than-normal concentration of spa chemicals and/or bacterial fragments. These dispersed spachemicals and/or bacterial fragments can be inhaled, and may result in breathing difficulties or lung damage in certain people suffering from acompromised immune system or respiratory infection. If you or other bathers are affected by this condition, please seek medical attention as soon aspossible.In addition to the above, properly clean and maintain your spa as follows:

• Follow all procedures in this owner’s manual and printed instructions on all water care (chemical) products packaging.• Test the water regularly to ensure proper levels of sanitizers, pH, and other water care requirements.• Drain, clean, and refill your spa with fresh water on a regular schedule, and in accordance with this owner’s manual.• Clean the filter(s) at least once per month.• Check to make sure you have proper circulation throughout your spa water system.• Have spa users bathe before entering the spa water.

SPA LEVELING PREPARATIONConcrete sloped at 1/2 inch (1.3 cm) per 10 feet (305 cm) is preferred so that rain water and water spillover will run off and not puddle underneaththe spa (water under the spa for long periods of time may cause the wood to deteriorate). Other options are brick, stepping stone, or blocks. It is important to note that soft surfaces, even when stepping stones are used to evenly distribute the weight of the spa, will have a tendency tosettle, thus resulting in an unleveled spa.NOTE: Placing the spa on grass or dirt may increase the amount of debris which is inadvertently brought into the spa water and may cause harmto your equipment as well as the spa surface, which is not covered under warranty.

Electrical Installation Page 5

SPA COVER INSTALLATION• Place the cover squarely on the spa.• Position the tie-down locks included with your cover on the side of the spa so that they are easily reached by the cover tie-down straps.

Allow for about 1/2” to 3/4” slack in the straps to make it easy to insert straps into locks and to compensate for vinyl shrinkage in cold weather.• Attach the locks with the screws provided and insert the cover tie-down straps into the locks.

NOTE: Keeping the cover in place any time the spa is not in use will reduce the amount of time theheater operates, thereby minimizing operating costs.

ELECTRICAL INSTALLATIONSELECTING THE VOLTAGE FOR YOUR SPAYour spa is designed to operate at either 115 or 230 volts, 60 Hz, unless it is the Mallorca® or La PalmaTM models which requires a dedicated 230 voltpower supply. When the spa is connected to 115 volts, the heater will provide approximately 1000 watts of heat only when the pump is operating inLOW speed and the thermostat is calling for heat. When the spa is connected to 230 volts, the heater will provide approximately 4000 watts of heatwhen the pump is operating in LOW or HIGH speed and the thermostat is calling for heat.All electrical connections must be made in accordance with the wiring information contained in the electrical control box or on the back of the fieldwiring access panel of the equipment module.

115 VOLT INSTALLATIONSpas provided with a factory- installed power supply cord are to be plugged into a grounded, grounding type, 115 volt, 20 ampere receptacle(Trinidad® and Sorrento® models). No other electrical appliance or fixture can be used on this circuit.IMPORTANT: Under NO circumstances should an extension cord be used. Use of an extension cord will seriously degrade the performance of theequipment module and can create an electrical hazard.

230 VOLT INSTALLATIONWhen using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hardwired direct to a GFCI-protectedsubpanel by a licensed electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.

ELECTRICAL REQUIREMENTS AND PRECAUTIONSYour Hot Spot® spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly wiredcircuit will negate many of the spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries. Pleaseread and follow the electrical installation requirements and instructions for your spa completely!

115-230 VOLT CONVERSION • SORRENTO(Model SOR) • TRINIDAD (Model TRI)Refer to the following instructions to convert your 115 volt Hot Spot spa to a 230 volt spa.NOTE: Converting the spa to 230 volts operation should only be done by an authorized service agent or a qualified electrician.The conversion requires a subpanel (230 volt) which may be purchased from your Authorized dealer. Ask for part # 38661.1. Disconnect the power cord from the house receptacle.2. Remove the screws and open the equipment compartment door.3. Remove the screws from the control box.4. Open the control box cover.5. Remove the power cord wires, and the power jumper wire (from line 2 and neutral) on the line side of the terminal block.6.

Operating Instructions Page 11

OPERATING INSTRUCTIONSSTART-UP AND REFILL PROCEDURESYour Hot Spot® spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. Asmall amount of water may have remained in the plumbing after testing and, as a result, may have spotted the spa shell or the spa siding prior todelivery. Before filling the spa, wipe the spa shell clean with a soft rag.The following instructions must be read and followed exactly to ensure a successful start-up or refill.

CAUTIONS• Do not fill the spa with hot water, as tripping of the high-limit thermostat may result.

• DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the spa automatically activates critical components within the spa,such as controls, heater, and other systems. If power is supplied to these components prior to the spa being filled, thecomponents will be damaged, and this may result in a non-warranty component failure.

• Do not use your spa after filling until all of the steps listed below are completed.

• Do not add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa®) sanitizer.

• Before filling your spa for the first time, remove the equipment compartment door and check to ensure that the unions on eitherside of the pump(s) and heater are hand-tight.

1. Ensure the drain is closed and remove the filter compartment cover, skimmer basket, weir, and filter. Then insert the end of a garden hose intothe filter hole and begin filling the spa. The water level of your Hot Spot spa should be maintained at a level one inch above the highest jet inthe spa. Reinstall the skimmer basket, weir, and filter once the spa is filled.IMPORTANT: Watkins Manufacturing Corporation does not recommend that the spa be filled with “softened” water, as this may damage thespa’s equipment.

2. Install SPA FROG bromine and mineral cartridges. See Spa Frog Replacement Instruction section and install the cartridge.IMPORTANT: Each time the spa is filled with water, you must remove and reinstall the SPA FROG cap, even if you are not replacingthe cartridge, in order to properly prime the jet pumps.

3. AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa. • 115 volt models: Connect the GFCI to the waterproof receptacle and push the RESET button on the GFCI.• 230 volt models: Open the door of the electrical subpanel and reset the GFCI breaker. Close and secure the subpanel door.

4. The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. To check the operation of the jetsystem and to purge any remaining air from the heating system, push the JETS button on the control pad twice (three times for Mallorca®) tomake the jet pump(s) run on high speed for one minute. Once the jet system is fully operational (as indicated by strong, non-surging jets),priming of the spa is complete. If you do not feel a steady stream of water from your jets, refer to the instructions for priming the pump in theSPA TROUBLESHOOTING section in the back of this manual.

5. Adjust Total Alkalinity (TA) to 125 ppm, Calcium Hardness (CH) to 150 ppm, then spa water pH to between 7.4 and 7.6. These procedures arelisted in the “Water Quality and Maintenance” section. IMPORTANT: Add spa water chemicals directly into the filter compartment after activating “Clean Cycle” (Press SET, then Jets button).

OPERATION NOTES:

1. Your spa is equipped with a ten-minute timer delay on the heating/maintenance mode. Whenever the jet pump has been turned off (and athree-degree temperature drop has occurred) or the temperature control has been turned up, it will take ten minutes before the low speed ofthe jet pump and heater become activated. Always push the JETS button to turn off the jet pump when exiting the spa. In the standard 115volt, 20 amp electrical configuration, the heating system does not operate simultaneously with the high speed pump. On the other hand, onthe 230 volt system, the heating system does operate simultaneously with the high speed pump.

2. The spa controller has an automatic two hour “time-out” feature should the high speed jet mode be left on inadvertently. After one hour ofcontinuous operation, the controller will automatically return to the maintenance/heating mode.

3. The spa controller also has a six-hour “time-out” feature should the light be left on inadvertently. After six hours of continuous operation,the controller will automatically turn the light off.

HEATING AND HYDROMASSAGE SYSTEMSThe Hot Spot® Spa uses a two-speed jet pump to operate its hydromassage jets and to circulate the spa water through the heating system (theMallorca® & La PalmaTM are also equipped with a single speed jet pump used for jets only). The low speed mode of the pump, which is activatedautomatically by the control thermostat, will cause the spa water to be drawn slowly in through the filter, the heater, and into the pump. Thepump, in turn, will push the water back into the spa through the jets. When the JETS button is pushed one time, the spa user can activate thelow speed of the jet pump. (The heater may or may not be on, depending on whether the control thermostat has indicated a demand for heat.)When the JETS button is pushed a second time, the high speed of the jet pump will be activated. (This will automatically deactivate the heater ifit is operating in a standard 115 volt 20 amp system.)In the 230 vollt electrical system, if a drop in the water temperature has occurred, the spa heater will operate simultaneously when the jet pumpis operating on high speed. On the other hand, in a standard 115 volt 20 amp electrical system, the spa heater will not operate simultaneouslywhen the jet pump is operating on high speed, even if a drop in the water temperature has occurred. In either electrical configuration, when thehigh speed mode of the jet pump is turned off, the spa will enter a ten-minute “tranquil mode.” During this time the heating system (andsimultaneous operation of the jet pump at low speed) will not operate (unless the JETS button is pushed), even if the water temperature hasdropped below the control setting. Once the ten-minute period has expired, the spa controller will switch to the maintenance mode and theheating system will be automatically activated.The Hot Spot Spa is equipped with a state-of-the-art heating system. The system uses an exclusive “flow through” No-Fault® stainless steel heater.

HYDROMASSAGE JETSThe larger jets in your spa allow you to re-direct the jet stream by changing the position of the nozzle.The Air Control lever is used to change the air intensity of all jets simultaneously.You can also regulate the force of the massage by rotating the jet face clockwise to reduce the force or counter-clockwise to increase the force.Notice that turning off the flow to some jets increases the flow to the other jets. To avoid damage to your spa’s plumbing and components, donot turn off more than half of these jets at the same time.Directional nozzles come standard on the Hot Spot models, however, a dual port rotary nozzle can be placed in any jet location desired. Thedirectional nozzles can be removed by rotating the tabs to either side of the nozzle then grasping the nozzle and gently pulling away from the jetfaceplate. ACCESSORY NOTE: dual port rotating nozzles are available from your Hot Spot dealer to replace the directional adjustable nozzles.

PRECISION® JETSPrecision jets are small. They are designed to perform a soft, soothing massage on your back and shoulders. Adjust their pressure using the AirControl lever.

AIR CONTROL SYSTEMAIR CONTROL VALVE: Turning the Air Control lever to the left position allows for the same volume of air to flow to all individual jets and Precisionjets simultaneously. The jet faceplate on the larger jets is then used to control the water intensity of each hydromassage jet. NOTE: Always turn the Air Control lever to the right position anytime the spa is not being used. This will help make the spa operate more quietlyand heat more efficiently when the vinyl cover is in place.

DIVERTER VALVE (LA PALMATM & SORRENTO® MODEL ONLY)The diverter valve on your spa allows you to direct the flow of water from the pump to several combinations of jets. The functions of this divertervalve can best be learned by experimentation as follows:1. Set all air controls to the “ON” position by rotating counterclockwise.2. Turn on the pump.3. Turn the handle on the diverter valve and see which groups of jets are affected. (Note that you can adjust the diverter valve to any position

between the two possible extremes to achieve the jet pressure that feels best to you.)IMPORTANT: Your spa is not designed to provide full power to all jets when the diverter valve is in the “mid” position.

Page 12 Operating Instructions

SAFETY EQUIPMENT A. GFCI: The Ground Fault Circuit Interrupter, located on the end of the power cord (115 Volt models only), is a safety device that is designed to

sense as little as 5 milliamps of electrical current leakage to ground. It is very important to protect a GFCI from rain and other moisture.Watkins Manufacturing Corporation recommends that the GFCI be tested before each use to ensure it is functioning correctly.

To test the GFCI:Cord-Connected 115 Volt, 20 Amp Models: Before each use, with the spa operating, push the TEST button (located on the front of theGFCI). The GFCI breaker should trip to the “off” position, disconnecting power to the spa. Reset the GFCI by pushing the RESET button. Thespa will now operate normally. If the interrupter does not perform in this manner, it is an indication of an electrical malfunction and thepossibility of an electric shock. Unplug the spa until the fault has been identified and corrected.230 Volt, Permanently installed or converted Models: The GFCI breaker is located inside the subpanel, before each use of the spa and with the unit operating, push the Test button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker by switching it completely off and then completely on. The switch should then stay on.

B. HEATER HIGH-LIMIT SWITCH: The heater high-limit sensor is located on the heater assembly. If for any reason the internal temperature of theheater exceeds 120°F (49°C), the high-limit circuit will trip and turn off the spa. The control panel display will display - - - -. The heater high-limit may be reset when the water temperature within the heater has cooled to approximately 110°F (43°C). Reset the heater high-limit bysimply disconnecting power to the spa for thirty seconds. The cause of the overheating must be located to prevent a recurrence. The mostcommon cause of limit-tripping is inadequate water flow through the heating system. This may be caused by an obstruction within the pumpwater lines (filter, pump intakes or internal plumbing), the non-function of the low-speed mode of the jet pump, or the malfunction of thecontrol thermostat. Once the cause has been identified and corrected, and the sensor has cooled, reset spa by simply disconnecting power tothe spa for thirty seconds.

C. PRESSURE SWITCH: The pressure switch is located inside the control box on the heater, and is designed to prevent heater operation duringa no or low flow condition. If for any reason flow through the heater is reduced or stopped, the pressure switch will trip. If the pressure switchhas detected a no or low flow condition _ . _ . _ . _ will display. The most common causes of inadequate heater flow are a dirty or cloggedfilter, obstruction in the plumbing lines, and non-operation of the low speed heat pump. Additionally, the control panel will display _ _ _ _ ifthe pressure switch senses flow through the heater when the jet pump is not activated. Contact your Authorized Service Technician if displayed.

D. CONTROL THERMOSTAT: The control thermostat helps regulate the temperature of the water. If for any reason something were to happen to this device, the READY icon on the control panel will flash. Contact your Authorized Service Technician.

SPA CONTROL PANELYour control panel consists of an LED display and convenient touchpads that allow you to set the water temperature and adjust theskim/filter cycle settings, lock spa temp, lock entire spa functions, aswell as control the hydrotherapy jets, and light from spa-side.

LED DISPLAYThe LED display on your spa-side control panel continually shows thespa’s set water temperature. In certain situations, it will also displayother messages. See TROUBLESHOOTING section.

SET BUTTONUse the set button to control clean cycle, filter cycle, locking and lightfunctions. To activate the desired mode, press the “SET” button. Whenthe “SET” icon flashes push the applicable button. The “SET” modeends after 3 seconds or when the “SET” icon stops flashing.

TEMPERATURE CONTROLThe set temperature range is from 80°F (27°C) to 104°F (40°C). Temperatures of any setting may rise slightly depending on the current use and

condition of your spa, and on outside temperature. Whenever power is disconnected and then reconnected to thespa, the water temperature setting will automatically return to the last temperature entered into the program. Pressing the Temp Up (▲) button displays the spa’s set temperature. To increase the set temperature, press the TempUp (▲) button again, once for each degree of increased temperature desired. If you hold the button down, the settemperature will increase by one degree every half second.

Pressing the Temp down (▼) button displays the spa’s set temperature. To decrease the set temperature, press the Temp down (▼) button again,once for each degree of decreased temperature desired. If you hold the button down, the set temperature will decrease by one degree every half second.

SLEEP MODEThe Sleep Mode operation is a feature that minimizes pump operation during quiet evening hours. For example, ifFilter Cycle 1 (F1) is set to activate at 8:00 a.m., by default, Filter Cycle 2 (F2) will activate at 8:00 p.m. (12 hours later).During 8:00 p.m. to 8:00 a.m., if the spa should call for heat, the pump and heater will activate to heat the spa undernormal temperature demand. However, when in Sleep Mode, should the spa call for heat, the pump and heater willbe suspended after Filter Cycle 2 (F2) until the activation of Filter Cycle 1 (F1), at 8:00 a.m. to minimize pump

activation during quiet evening hours. Important: Power-up of the spa starts the F1 sequence. In order for the sleep mode to work in the evening hours, the spa must be powered up inthe early morning hours. The Sleep Mode will always be active the 6-12 hours between the end of (F2) and the begining of (F1) depending on howthe filter cycle program is set. Note: If temperature drops below 80 degrees, heater will automatically activate to prevent spa from freezing.To activate Sleep Mode feature, press and hold Temp Up (▲) & Temp Down (▼) buttons together for 3 seconds. This will activate the feature andoverride the normal temperature demand. When these buttons have been engaged, a Moon & Stars icon (Sleep Icon) will appear in the display ofthe control panel, indicating this feature has been activated. To deactivate this feature, simply press and hold Temp Up (▲) & Temp Down (▼)buttons together for 3 seconds once again.

LOCKING FEATURESThe locking features, TEMPERATURE LOCK and SPA LOCK, are enabled from the control panel by a specific combination of buttons. Onceenabled, a lock will remain active until the specific button combination is applied to disable the lock. Even if power is disconnected from the spaand soon thereafter reapplied (such as a power outage), the lock will remain in place.

Water Quality and Maintenance

WATER QUALITY AND MAINTENANCEIt’s important to have clean water. Water maintenance is one of the least understood, yet most important areas of spa ownership. Your dealer canguide you through the process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend onyour water’s mineral content, how often you use your spa, and how many people use it. Watkins recommends that you either use an entirely chlorine-based system, or an alternative system which uses silver ions (the FreshWaterAg+

®

silver ion purifier). Watkins recommends the use of Hot Spring® FreshWater® products. These are available from authorized Hot Spot® dealers.

GENERAL INFORMATIONTHE THREE FUNDAMENTAL AREAS OF WATER MAINTENANCE:

• Water Filtration• Chemical Balance/pH Control• Water Sanitation

Water Sanitation is the responsibility of the spa owner, achieved through the regular and periodic (daily, if necessary) addition of an approvedsanitizer. The sanitizer will chemically control the bacteria and viruses present in the fill water or introduced during use of the spa. Bacteria andviruses can grow quickly in undersanitized spa water.The water’s chemical balance and pH control are also the responsibility of the spa owner. You’ll have to add chemicals to maintain proper levels ofTotal Alkalinity (TA), Calcium Hardness (CH) and pH. Proper water balance and pH control will minimize scale buildup, extend the life of the spa,and allow the sanitizer to work at top efficiency.

METHODS FOR TESTING THE SPA WATER Accurate water testing and analysis is an important part of effectively managing your spa water. You must have the ability to test for:

• Total Alkalinity (TA)• Calcium Hardness (CH)• pH• Sanitizer

Two types of testing methods are recognized and recommended by Watkins:The Reagent Test Kit is a method which provides a high level of accuracy. The reagents come in either liquid or tablet form.Test Strips are a convenient testing method used by many spa owners. Keep in mind that test strips are susceptible to heat and moisturecontamination, which will result in inaccurate readings. IMPORTANT: Always read and carefully follow the directions included with the Test Kit or Test Strips to ensure the accuracy of the test results.

BASIC CHEMICAL SAFETY When using chemicals, read the labels carefully and follow directions precisely. Though chemicals protect you and your spa when used correctly,they can be hazardous in concentrated form. Always observe the following guidelines:

• Allow only a responsible person to handle spa chemicals. Keep them out of the reach of children.• Accurately measure the exact quantities specified, never more. Do not overdose your spa.• Handle all containers with care. Store in a cool, dry, well ventilated place.• Always keep chemical containers closed when not in use. Replace caps on their proper containers.• Don’t inhale fumes or allow chemicals to come in contact with your eyes, nose, or mouth. Wash your hands immediately after use.• Follow the emergency advice on the product label in case of accidental contact, or if the chemical is swallowed. Call a doctor or the local

Poison Control Center. If a doctor is needed, take the product container along so that the substance can be identified.• Don’t let chemicals get on surrounding surfaces or landscaping. • Don’t use a vacuum cleaner to clean up chemical spills.• Never smoke around chemicals. Some fumes can be highly flammable.• Don’t store any chemicals in the spa equipment compartment.

HOW TO ADD CHEMICALS TO THE WATERIMPORTANT: All spa water chemicals (other than Spa Frog® cartridges), including MPS+ (shock), chlorine, granulated pH increaser or decreaser,granulated total alkalinity increaser, calcium hardness increaser, liquid stain and scale inhibitor, and liquid defoamer must always be added directlyinto the filter compartment while the jet pump is running in high speed mode, and it must run for a minimum of ten minutes.

Water Quality and Maintenance Page 21

To Administer Spa Water Chemicals:1. Fold back the cover. Carefully remove and set aside the filter compartment cover (Trinidad® does not have a filter cover).2. Push the JET button twice to activate the jet pump’s high speed mode.3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on

your hands, in your eyes, on the spa shell surface or on the siding.4. After ten minutes, shut off the jet pump and close and lock the cover to complete the procedure. Risk of Drowning: Never leave an open spa

unattended!WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the

recommended range before using the spa.IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT” NOTE: After administering a super chlorination treatment or non-chlorine shock to your spa, leave the cover open for a minimum of twenty minutes to allow the oxidizer gas to vent. A high concentration of trappedoxidizer gas which may exist as a result of the shock treatment (not daily sanitation) may eventually cause discoloration or vinyl degradation to thebottom of the cover. This type of damage is considered chemical abuse and is not covered under the terms of the limited warranty.

THE HOT SPOT! SPA WATER MAINTENANCE PROGRAMEach step in your water maintenance program is dependent on the completion of the previous steps. Omitting a step or failing to reach therecommended range may cause an imbalance in your water’s chemistry. Unbalanced water chemistry can damage the spa and its components aswell as cause discomfort for the user.

FILLING THE SPA WITH WATERA. To prevent contaminants from entering the spa, Watkins Manufacturing Corporation recommends using the FreshStart®10,000 pre-filter when

filling the spa with water. Always fill the spa through the filter compartment.WARNING: DO NOT use the FreshStart10,000 pre-filter if you plan to use granular bromine or BaquaSpa® as your sanitizer.

B. The FreshStart10,000 pre-filter is designed to remove unwanted contaminants such as rust, dirt, detergents and algae from the fill water.Dissolved minerals and metals such as lead, calcium, copper and iron are not removed.

C. Instructions are included with the FreshStart10,000 pre-filter. When the spa is filled, proceed to the Start-Up and Refill Procedures on page 11.

BALANCING THE TOTAL ALKALINITY (TA)A. The recommended Total Alkalinity (TA) for your spa water is 125-150 ppm.B. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA is

referred to as the water’s “pH buffer”. In other words, it’s a measure of the ability of the water to resist changes in pH level.

C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or scaling of the spacomponents. Low TA can be corrected by adding Hot Spring

®FreshWater

®pH/Alkalinity Up or sodium hydrogen carbonate.

D. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult to bring down. It can be lowered by adding Hot SpringFreshWater pH/Alkalinity Down or sodium bisulfate.

E. Once the TA is balanced, it normally remains stable, although the addition of more water with a high or low alkalinity will raise or lower the TAreading of the water.

F. When the Total Alkalinity is within the recommended range, proceed to the next step.

BALANCING THE CALCIUM HARDNESS (CH)A. The recommended Calcium Hardness (CH) level for your spa is 150-200 ppm.B. Calcium Hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the corrosive nature of the spa’s

water. That’s why calcium-low water (commonly known as “soft” water) is not recommended. It is very corrosive to the equipment, and cancause staining of the spa shell. If the calcium level is too low, we recommend using HotSpring FreshWater Calcium Increaser to bring thecalcium hardness level to within the recommended range.

C. If the CH is too high (commonly known as “hard” water), formation of scale on the spa’s shell surface and equipment can result. CH can bedecreased by dilution – a mixture of 75% hard and 25% soft water will usually yield a reading within the correct range. If soft water isnot available or practical for you, a stain and scale inhibitor, such as Hot Spring FreshWater Stain and Scale Defense, should be added to thespa water, according to label instructions.

D. Once the CH is balanced, it normally remains stable, although the addition of more water with a high or low calcium content will raise or lowerthe CH reading of the water.

E. When the Calcium Hardness is within the recommended range, proceed to the next step.


BALANCING THE PHA. The ideal pH level for your spa water is 7.4-7.6.B. The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those

below 7 are acidic. Maintaining the proper pH level is extremely important for:• Optimizing the effectiveness of the sanitizer.• Maintaining water that is comfortable for the user.• Preventing equipment deterioration.

C. If the spa water’s pH level is too low, the following may result:• The sanitizer will dissipate rapidly.• The water may become irritating to spa users.• The spa’s equipment may corrode.

If the pH is too low, it can be increased by adding sodium hydrogen carbonate, or Hot Spring

®FreshWater

®pH/Alkalinity Up, to the spa water.

D. If the pH level is too high, the following may result:• The sanitizer is less effective.• Scale will form on the spa shell surface and the equipment.• The water may become cloudy.• The filter cartridge pores may become obstructed.

If the pH is too high, it can be decreased by adding sodium bisulfate, or Hot Spring FreshWater pH/Alkalinity Down, to the spa water.

NOTE: After adding sodium hydrogen carbonate, or sodium bisulfate, wait two hours before testing the water for pH. Measurements taken toosoon may not be accurate.E. It is important to check the pH on a regular (weekly) basis. The pH will be affected by the bather load, the addition of new water, the addition

of various chemicals, and the type of sanitizer used.F. When the pH is within the recommended range, proceed to the final step.

MAINTAINING THE SANITIZER LEVELA. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same

time, you don’t want too high a sanitizer level, or it can irritate your skin, lungs and eyes.B. Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.C. Watkins recommends the following sanitizer:

• Spa Frog® sanitizing system (mineral and bromine)C. Watkins also approves the following sanitizers:

• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)• Baqua Spa® (please consult your Baqua Spa manual for instructions on the use of this product).• Brominating Concentrate (one step granular bromine)WARNING: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid,

or any type of sanitizer which is not recommended by Watkins Manufacturing Corporation.


SPA FROG! WATER CARE SYSTEMThe SPA FROG WaterCare system is comprised of the following products:

• TThhee SSPPAA FFRROOGG mmiinneerraall ccaarrttrriiddggee that introduces minerals into the spa water, inhibiting bacteria growth. When combined with MPS itoxidizes particulates in the spa water.

• TThhee SSPPAA FFRROOGG BBrroommiinnee ((BBCCDDMMHH)) is the only recommended sanitizer that will work in conjunction with the Spa Frog mineral cartridge inthis system.

• MMoonnooppeerrssuullffaattee ((MMPPSS)) is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, and improvewater clarity.

• FreshWater®

III high output ozone system uses Corona Discharge technology to produce a high concentration of ozone, which is injected into the spa water.

If the spa is being used over anextended period of time, such as a whole afternoon or evening, additional sanitizer will be needed. A weekly “shock treatment” is required. The shock treatment quickly destroys any remaining contaminants while revitalizing the bromine in thewater. To weekly “shock treat” your spa you may use MPS (sodium dichlor may also be used). Sodium dichlor may be a more appropriate weekly shockfor those users that experience heavy bather load conditions. IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer.

SPA FROG CARTRIDGE REPLACEMENT INSTRUCTIONSThe SPA FROG bromine cartridge should be replaced every 2-4 weeks, depending on User Load. The SPA FROG mineral cartridge should bereplaced every 4 months. When replacing the mineral cartridge, it is highly recommended that the spa be drained and refilled at the same time.After refilling the spa with water, balance the Total Alkalinity (A), Calcium Hardness (CH) and pH to the recommended levels. Shock the spa byadding MPS.To replace SPA FROG cartridges, follow these steps:1. Turn off power to the spa.2. Unscrew SPA FROG cap on top edge of spa.3. Turn handle counter-clockwise.4. Lift cartridge holder up and out of spa.5. Turn top cap of mineral cartridge to setting #6 (The mineral cartridge should last 4 months.) Turn top cap of bromine cartridge to setting #7.

NNOOTTEE:: Adjust bromine cartridge setting down by one setting each day until a residual of 1.0 - 2.0 ppm level of bromine is established. (The bromine cartridge should last 2-4 weeks.)

6. Snap bromine cartridge in at bottom of holder and mineral cartridge on top.NNOOTTEE:: It is important that the bromine cartridge is on bottom; otherwise, the bromine cartridge could be dispensed prematurely.

Always allow the sanitizer level to fall to the recommendedrange before using the spa.IIMMPPOORRTTAANNTT:: Each time the spa is filled with water, you must remove and reinstall the SPA FROG cap, even if you are not replacing the cartridge,in order to properly prime the jet pumps.

FOLLOWING THE SPA FROG SANITIZER ROUTINEDuring the first month of ownership, measure the sanitizer residual daily in order to establish the correct setting on cartridges for User Load andUsage Time versus Sanitizer Needed.

• The User Load of the spa is the number of times anyone enters the spa.• The Usage Time is simply the amount of time a user spends in the spa.• Sanitizer Needed is the amount needed to accomodate the number of users and their combined usage time.

For example, two spa users who regularly use the spa once an evening for twenty minutes create a specific and somewhat consistent demand onthe sanitizer. During the first month of ownership, these two users can determine exactly how much sanitizer to use in order to maintain the properresidual. If, at any time the user load and/or usage pattern changes dramatically (i.e. invited guests), the frequency of sanitizer required increasesdramatically. The greater the usage time, or the bather load, the faster the residual value is diminished.

DO’S AND DON’TSDO check your bromine chemical level prior to each use.

• DO change the SPA FROG® mineral cartridge every 4 months.• DO test Total Alkalinity and pH weekly.• DO use MPS for spas only, such as Hot Spring® MPS Chlorine-Free Oxidizer.• DO store all chemicals in a tightly sealed container in a cool, dry place.• DON’T use sodium bromide or biguanides. These are an active sanitizer and will combine with the silver ions to inactivate them.• DON’T use a water clarifier. Clarifiers will cause the spa water to become cloudy.• DON’T use the FreshWaterAg+

® silver ion purifier cartridge with SPA FROG.

BROMINEA. Sanitizing chemicals, such as bromine, are oxidants that kill bacteria and viruses in the water. If you are using the SPA FROG system, the

recommended bromine level for your spa water is 1.0 - 2.0 ppm. If you are not using the SPA FROG system, your bromine level should bebetween 3.0 - 5.0 ppm.

B. Watkins Manufacturing Corporation recommends the use of granulated bromine for sanitizing the water. Granulated bromine is preferredbecause it is totally soluble, dissolves quickly and is nearly pH neutral.

C. Maintaining the proper level of bromine during use is extremely important.D. If the bromine level is too low, bacteria and viruses can grow rapidly in the warm water.E. If the bromine level is too high, the water can cause discomfort to the user’s eyes, lungs and skin. SSiimmppllyy aallllooww ssoommee ttiimmee ttoo ppaassss..F. When the bromine level is within the recommended range, the spa is ready to be enjoyed.

WARNING: There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has specificchemical characteristics. It is extremely important that the one you choose is specifically designed for use in spas. Use of an incorrect productsuch as tri-chlor, which has a very low pH (2.6), dissolves too quickly in hot water resulting in extremely high levels of chlorine, and is designedfor concrete or plaster swimming pools, WILL cause damage to your spa. Use of a liquid, or any type of compressed bromine or chlorine,acid, or any type of sanitizer which is not recommended by Watkins Manufacturing Corporation WILL damage your spa and is specifically notcovered under the terms of the limited warranty.IMPORTANT: Granulated chlorine (sodium dichlor) will degrade if stored improperly. We recommend purchasing chlorine in one, two, or fivepound containers and storing it in a cool, dry place to maintain its potency.

SUPER CHLORINATIONSuper Chlorination is designed to “burn-off” the build-up of chloramines (used chlorine), to eliminate the chlorine smell and to allow the properlevel of free chlorine to be maintained.When giving your water a super chlorination treatment, open the cover at least half way for twentyminutes to allow the chlorine gas to vent off. The high concentration of chlorine gas which mayexist as a result of super chlorination (not daily sanitation) may eventually cause discoloration ordegradation to the bottom of the cover, which would not be covered under the terms of yourwarranty.

SUPPLEMENTAL WATER MAINTENANCEProper water sanitation and mineral balance (pH control) are absolutely essential for a completespa water maintenance program. Here are three other popular water additives that are optional:Mineral Deposit InhibitorsAs water evaporates from your spa and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping thecover on the spa whenever possible.) The spa water may eventually become “hard” (Calcium Hardness too high) enough to damage the heater bycalcifying its surface. Proper pH control can minimize this.Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.Occasionally, high iron or copper content in the water may produce green or brown stains on the spa. A mineral deposit inhibitor, such as HotSpring® FreshWater® Stain and Scale Defense, may help to reduce these metals.


NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter (in-line pre-filter such asthe FreshStart®

10,000 pre-filter) will help to remove many of the larger particles during the filling of the spa. In-line pre-filters can be purchased atyour local Hot Spot® Spa Dealer.

Foam InhibitorsSpa water requires changing due to the build-up of soap in the water. Typically, soap will cause the spa water to foam when the jets are used.Soap is introduced into the spa water from two sources; users’ bodies, which retain a soap residue after showering, and swimming apparel, whichretains soap after washing.Foam inhibitors, such as Hot Spring® FreshWater® Defoamer, can suppress foam, but cannot remove soap from the water. Soap is very difficult toremove from the water because soap is not oxidized by any chemical added to the spa. Only ozone can oxidize soap.Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin, which is impossible to remedy.When this occurs, it’s time to drain and refill the spa. Depending on the soap input, the water should last about 4 months before needing to bedrained.

OZONE (OPTIONAL) The FreshWater® III high output ozone system is the Watkins recommended ozone purification system for your spa. The FreshWater III ozonesystem utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing ultraviolet light (UV)ozone systems.The FreshWater III high output ozone system greatly enhances the quality of the spa water when used to supplement the spa owner’s regularwater maintenance program. Contrary to some information circulated throughout the pool and spa industry regarding ozone systems, ozone CANNOT be used as a single-source sanitizer, water clarifier, anti-foamer, and mineral chelating agent. A secondary-source sanitizer must be used tomaintain 2.0 ppm (2.0 mg/L) of Free Available Chlorine (FAC). Watkins Manufacturing Corporation recommends that a chemical maintenanceprogram based on recognized and documented industry standards still be followed when using an ozone purification system to assure watersanitation and the highest quality purified water.

Cleaning the Ozone InjectorOn occasion, a mineral build-up may clog the ozone injector causing a lack of flow or low flow of ozone bubbles. To prevent this, refer to thefollowing instructions to clean the injector:1. Disconnect power to the spa.2. Access the equipment compartment. 3. Locate the ozonator in the equipment compartment and unplug the ozonator from the control box.4. Place 16 ounces (1/2 liter) of white vinegar into a container such as a cup or bucket. Place the container on the equipment compartment floor.

NOTE: White vinegar will not damage any of the spa components.5. Carefully loosen the long Tygon / Kynar tubing to the bottom of the ozonator. A liquid substance may be found inside the tubing. If a liquid

substance is present, BE CERTAIN NOT TO COME INTO CONTACT WITH THE LIQUID (SEE WARNING ABOVE).6. Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.7. Reconnect power to the spa.8. Run the spa until all 16 ounces (1/2 liter) of the vinegar are gone. This should allow an ample flow of vinegar to be run through the injector and

clear the blockage.9. Disconnect power to the spa.10. Remove the empty cup or bucket.11. Reinstall the tubing to the bottom of the ozonator.12. Plug the ozonator into the control box.13. Close the equipment compartment door.14. Reconnect power to the spa.

Nitric acid accumulates in the air lines of the ozonator and injector. Nitric acid will causesevere chemical burns if direct skin contact is made, so always wear protective gloves,glasses and clothing when working on the ozonator or injector lines. To prevent inhalationor ingestion of the nitric acid, DO NOT blow or inhale with your mouth to any of theadapters, fittings or tubing of the ozonator or injector air lines.

WARNING WARNING

IMPORTANT: When using the FreshWater® III high output ozone system, the circulation cycle must be activated to ensure adequate ozonecirculation. Refer to the circulation cycle in the HEATING AND HYDROMASSAGE SYSTEM section for more information.

DO’S AND DON’TS• DO add all chemicals slowly into the filter compartment with the jet pump operating on high speed for ten minutes.• DO use special care if using baking soda to clean either the interior or exterior plastic surfaces.• DO use only a granular form of sanitizer.• DON’T use swimming pool (muriatic) acid to lower pH.• DON’T splash pH increaser additives on the siding.• DON’T use Compressed Sanitizers.

The use of bromine sticks or tablets in floaters, which may become entrapped in a lounge or cooling seat (or sink to the spa floor), have beenshown to cause discoloration of or surface distress to a spa’s shell.

• DON’T use a floater type sanitization system as a low or no maintenance solution to your spa maintenance program.The spa shell can easily withstand the effects of a properly administered sanitizer. Floating dispensers can become trapped in one area and causean over-sanitization (or chemical burn) of that particular area. If the dispenser setting is too high, the high concentration can discolor the spa shell and damage the underside of the cover.Automatic floating dispensers have a tendency to either over-brominate or under-brominate as the rate of erosion varies greatly. Damage to thespa and cover can occur very quickly.

WARNING: Watkins Manufacturing Corporation DOES NOT recommend the use of any floating chemical dispenser. Damage to the spa shellor components caused by a floating chemical dispenser is specifically not covered under the terms of the limited warranty.

• DON’T use a sanitizer which is not designed for spas.• DON’T use household bleach (liquid sodium hypochlorite).• DON’T broadcast or sprinkle the chemicals onto the water surface. This method may cause chemically-induced spa surface blistering

(chemical abuse).

COMMON WATER CHEMISTRY QUESTIONSQuestion: Why can’t I use a floater to sanitize my spa water?Answer: Watkins Manufacturing Corporation does not recommend the use of a floater for three reasons: 1. The floater is unable to control the rate at which the sanitizer is dissolved into the water. When a floater is first placed in a spa, the sanitizer

level can be extremely high. High sanitizer levels can chemically burn or discolor the spa’s shell or the underside of the cover. Then, after aperiod of time, the sanitizer level dispensed by the floater will fall to near zero. A low sanitizer level will allow viruses, bacteria, or algae to grow.

2. Floaters tend to stay in one area of the spa most of the time (usually over the cool-down seat), causing this area to be exposed to extremesanitizer levels.

3. The floater may allow pieces of the highly concentrated sanitizer to fall out and settle on the floor or seat of the spa shell. These pieces ofsanitizer will chemically burn (blister) the spa shell. Although your spa shell is specifically designed to resist the effects of spa chemicals, nospa surface can withstand this type of highly concentrated chemical. Remember, chemical abuse is specifically not covered under the termsof the warranty.

Question: When I open my spa, I smell chlorine. How do I get rid of this smell?Answer: There are two types of chlorine in your spa. The first is the Free Available Chlorine, which is the chlorine available to sanitize your spa.This Free Available Chlorine does not have an odor. The second is Chloramine, which is residue from chlorine already expended. Chloramineshave a strong chlorine odor. The smell from Chloramines can be eliminated by “shocking” the water. If you smell chlorine in the water, your spa isreminding you to add a shock treatment.Question: Why can’t I fill my spa with soft water?Answer: Soft water is essentially the same as regular water except that most or all of the calcium has been replaced by sodium. Soft water maybe corrosive to the heater and other components. Replacement of spa components damaged by soft water is extremely expensive.Question: I am trying to reduce the number of chemicals to which my family is exposed. Do I really need to use so many chemicals and in suchlarge amounts?Answer: While over-exposure to any chemical can be unhealthful, many low levels of chemicals are effective and beneficial. In the case of spawater, the chemicals recommended in the Hot Spot® Spa Water Maintenance program are needed to protect the user from water-borne pathogens(disease-causing microbes) and to prevent corrosion of spa components. Question: Why isn’t water chemistry damage covered by the warranty?Answer: The chemical levels and water quality of the water in the spa are under your direct control. With proper basic care, the spa will providemany years of hot water relaxation. If you are unsure about any chemical or its usage in the spa, contact your Authorized Dealer or WatkinsManufacturing Corporation.


Maintenance and Spa Care

WATER TERMINOLOGYThe following chemical terms are used in this Water Quality and Maintenance section. Understanding their meaning will help you to betterunderstand the water maintenance process.Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike chloramines,bromamines have no pungent odor and are effective sanitizers.Bromine: A halogen sanitizer (in the same chemical family as chlorine). Bromine is commonly used in stick, tablet, or granular form. See the DOsand DON’Ts of Spa Water Maintenance for additional information.Calcium Hardness: The amount of dissolved calcium in the spa water. This should be approximately 150-200 ppm. High levels of calcium cancause cloudy water and scaling. Low levels can cause harm to the spa equipment.Chloramines: Compounds formed when chlorine combines with nitrogen from body oils, urine, perspiration, etc. Chloramines can cause eyeirritation as well as having a strong odor. Unlike bromamines, chloramines are weaker, slower sanitizers.Chlorine: An efficient sanitizing chemical for spas. Watkins Manufacturing Corporation recommends the use of sodium dichlor-type granulatedchlorine. This type is preferred because it is totally soluble and nearly pH neutral.Chlorine (or Bromine) Residual: The amount of chlorine or bromine remaining after chlorine or bromine demand has been satisfied. The residualis, therefore, the amount of sanitizer which is chemically available to kill bacteria, viruses and algae.Corrosion: The gradual wearing away of metal spa parts, usually caused by chemical action. Generally, corrosion is caused by low pH or by waterwith levels of TA, CH, pH or sanitizer which are outside the recommended ranges.DPD: The preferred reagent used in test kits to measure the Free Available Chlorine.Halogen: Any one of these five elements: fluorine, chlorine, bromine, iodine and astatine.MPS: Monopersulfate is the non-chlorine oxidizer used with the FreshWaterAg+® silver ion purification system.Oxidizer: The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine,and improve water clarity.Pathogen: A microorganism such as bacterium that cause disease.pH: The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.4 to 7.6. Below 7.0 (considered neutral), thespa water is too acidic and can damage the heating system. Above 7.8, the water is too alkaline and can result in cloudy water and scaleformation on the shell and heater.ppm: The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.Sanitizer: Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can causedisease and infection in spa water.Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines and clog filters. Generally, scaling is caused by mineralcontent combined with high pH. Additionally, scale forms more readily at higher water temperatures.Shock Treatment: Also known as “super-chlorination” when chorine is used. Shock treatment is a process of adding significant doses of a quickdissolving sanitizer (sodium dichlor is recommended) to oxidize non-filterable organic waste and to remove chloramines and bromamines.Total Alkalinity: The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for pH control.If the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The desired range of TA in spawater is 125 to 150 ppm.

MAINTENANCE AND SPA CAREFILTER MAINTENANCEAt least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove leaves, foreign matter, and debris. It isvery important to keep your spa filter cartridge clean and free of particles to ensure proper water flow. A clean filter permits the hydrotherapysystem to function properly and also allows more efficient filter cycles. Depending on how frequently your spa is used, we recommend cleaningthe spa filter cartridge every four weeks. If this is not done, the filter may clog and restrict water flow, which causes improper filtration and poor jetperformance.

WARNING: The frequency and duration of use, and the number of occupants all contribute to determining the appropriate time between filtercleanings. More use means that more frequent filter cleanings will be required.

FILTER CARTRIDGE REMOVAL AND CLEANING FOR MALLORCA®, SORRENTO® & TRINIDAD®

Turn the spa OFF or turn the power to the spa OFF, then proceed as follows:1. Push down slightly and turn filter basket counterclockwise to unlock,

then pull the basket and weir out. 2. Carefully pull up the filter cartridge and bring it out of the spa.3. Rinse cartridge using a garden hose. Rotate and separate filter

pleats while spraying water to remove all debris possible. Let thefilter dry and then look for calcium deposits (scaling) or an oil film. Ifyou find these, you will need to deep clean your filter cartridge with a“spa filter cleaning” solution to break down and remove mineraldeposits and oils.

4. To return basket and weir, insert and rotate clockwise to lock intoposition.

FILTER CARTRIDGE REMOVAL AND CLEANING FORLA PALMATM

1. Disconnect the spa from the power supply by turning the power to thespa OFF.

2. Remove and carefully set aside the filter compartment cover.3. Remove any floating items from within the filter compartment.4. Turn the filter retainer handle (located on the top of the filter cartridge)

counterclockwise until the retainer can be removed from the filterstandpipe.

5. Remove the filter retainer and cartridge.SERVICE NOTE: Never remove the filter standpipe(s) when debris ispresent in the filter compartment. Debris may find its way into theinternal plumbing which may result in blockage. NEVER REMOVESUCTION FITTINGS!

6. Always clean the filter using a filter degreaser, such as Hot Spring®

FreshWater® Filter Cleaner, to remove mineral and oil build-up. Simplysoak the filter in the degreaser according to the package directions,then place the filter on a clean surface and spray until clean using agarden hose. It may be necessary to rotate the filter while spraying toremove any debris lodged between the filter pleats.

7. To reinstall the filter cartridge, reverse the order of steps in which itwas removed. Do not overtighten

CARE OF THE SPA PILLOWSThe spa pillows will provide years of comfort if treated with care. Theyhave been positioned above the water level to minimize the bleachingeffects of chlorinated water and other spa water chemicals. To extend theirlife, whenever the spa shell is being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with a mild soap andwater solution. ALWAYS rinse off the spa pillows thoroughly to remove any soap residue. If the spa is not going to be used for a long period of time(that is during a vacation or if the spa is winterized), or when the spa water is being super-chlorinated, the spa pillows should be removeduntil the next use of the spa.

To remove and replace the spa pillows:1. Carefully lift one end of the pillow away from the spa shell.2. Continue lifting one end until all pillow retainers are released from the pillow.IMPORTANT: Just pulling the pillow straight up and out of the shell recess will eventually damage the pillow.

Maintenance and Spa Care

CARE OF THE EXTERIORSPA SHELLYour Hot Spot® spa has an acrylic like shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag or a nylon scrubber shouldeasily remove most dirt. Most household chemicals are harmful to your spa’s shell. Watkins Manufacturing Corp. recommends Soft Scrub® andWindex®. These are the only products which have passed the manufacturer’s tests. Sodium bicarbonate (baking soda) can also be used for minorsurface cleaning. Always thoroughly rinse off any spa shell cleaning agent with fresh water. SERVICE NOTES:

1. Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your Hot Spot dealer for a stain and scale Inhibitor to useif your spa water has a high concentration of dissolved minerals.

2. The use of alcohol or any household cleaners other than those listed to clean the spa shell surface is NOT recommended. DO NOT use anycleaning products containing abrasives or solvents since they may damage the shell surface. NEVER USE HARSH CHEMICALS! Damage tothe shell by the use of harsh chemicals is not covered under the warranty. IMPORTANT: Some surface cleaners contain eye and skin irritants. Keep all cleaners out of the reach of children and use care when applying.

CARE OF THE SPA COVERWARNING: The cover is a manual safety cover that meets or exceeds all prevailing requirements of ASTM Standards for spa safety covers

when installed and used correctly as of the date of manufacture. Non-secured or improperly secured covers are a hazard. Open the cover to itsfully open position before use.

VINYL COVERThe vinyl spa cover is an attractive, durable foam insulation product. Monthly cleaning and conditioning are recommended to maintain its beauty.

To clean and condition the vinyl cover:1. Remove the cover from the spa and gently lean it against a wall or fence.2. With a garden hose, spray the cover to loosen and rinse away dirt or debris.3. Using a large sponge and/or a soft bristle brush, and using a very mild soap solution (1 teaspoon dishwashing liquid with 2 gallons of water) or

baking soda (sodium bicarbonate), scrub the vinyl top in a circular motion. Do not let the vinyl dry with a soap film on it before it can be rinsed clean.4. Scrub the cover’s perimeter and side flaps. Rinse clean with water.5. Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.

SERVICE NOTE: To remove tree sap, use cigarette lighter fluid (not charcoal lighter fluid). Use sparingly, and rinse with a saddle soap solutionimmediately afterwards, then wipe dry.

Important reminders:• DO remove snow buildup to avoid breakage of the foam core from the additional weight of the snow.• DO lock cover lock straps to secure the cover when the spa is not in use.• DO NOT drag or lift the spa cover using either the flaps or the cover lock straps.• DO NOT walk, stand, or sit on the cover.• DO NOT place any metal or heat transferring object on the cover or place any type of plastic tarp or drop cloth over the cover as this may

result in a melted foam core, which would not be covered under the warranty.• DO NOT use any lifting mechanisms, chemicals or cleaners except those recommended by Watkins® Manufacturing Corporation or its

Authorized Sales and Service Dealer.

WOOD SPA CABINET This spa cabinet is available on Mallorca®, Sorrento® & Trinidad® spas and is constructed of high-quality wood. The wood cabinet is factory-sealedwith a lightly tinted stain for beauty and protection. As with all wood products, prolonged exposure will cause discoloration and drying. Do not usewood sealers or wood furniture-type oils such as tung, teak or lemon to seal the cabinet, as they will cause the wood to blacken. Discoloration oraging of the redwood cabinet is considered natural and is not covered by the limited warranty.NOTE: Always test a small area (such as one or two vertical corner boards) or your spa cabinet for stain compatibility before applying a non-recommended stain.

SIMULATED SPA CABINET This cabinet is available on La PalmaTM model, Mallorca & Sorrento models. Simulated wood consists of a rigid polymer that combines thedurability of plastic, with the beauty of wood. Simulated wood won’t crack, peel, blister, or delaminate even after prolonged exposure to theelements.Cleaning of Simulated wood consists of simply spraying the cabinet with a mild soap and water solution to remove any stains and residue.

DRAINING YOUR SPA1. TURN OFF OR DISCONNECT POWER FROM THE SPA.

2. Remove the equipment compartment access door.3. Locate the drain cap. Lift drain hose above the water level (requires cutting

plastic tie the first time).4. Unscrew and remove the drain cap.5. Attach drain hose to garden hose and direct to an appropriate draining area.

Maintain hose below water line.6. After your spa is empty, clean the shell and filter cartridge.7. After cleaning, remove garden hose and put drain cap back in place.8. Replace the equipment compartment access door.

NON-OPERATION IN COLD CLIMATEIf the spa is to be left unused for an extended period of time in areas whereFREEZING TEMPERATURES DO NOT OCCUR, it may be desirable to turn theheater to the lowest temperature. The automatic filter cycles will keep the spa water clean and sparkling. When preparing the spa for use, checkthe water chemistry to assure correct chlorine or bromine and pH levels. You can keep the water in the spa during the time of year when freezing at the spa location may occur. If a freeze condition is detected, the pumpand heater will be activated automatically to circulate the water in low speed. However, CAUTION must be used with this approach. In the event ofelectrical power interruption, regardless of the cause, the heater and pump will stop operating and freeze protection will be lost, possibly resultingin freeze damage to the spa, spa plumbing and/or components. Such damage is not covered by warranty.

WINTERIZING YOUR SPAIf the spa is located where freezing temperatures occur, and you do not intend to use your spa for an extended period, follow steps 1 through 7outlined in “Draining Your Spa” (above) then complete the steps below. IMPORTANT: The following steps should protect your spa from freezing damage provided these instructions are followed exactly. For maximumprotection against freeze damage to your spa, Watkins Manufacturing Corporation recommends contacting your local Hot Spot® dealer toschedule an in-home Propylene glycol (anti-freeze) Winterizing Service plan.NOTE: MAKE CERTAIN ALL POWER TO THE SPA IS OFF and all water hasbeen drained from the spa before you continue.1. It will be necessary to remove all water from the interior plumbing.2. Remove the floating weir basket and filter cartridge. Clean the filter cartridge

and store in a dry place. Attach the vacuum hose to the vacuum side of the shop vac and thoroughly dry the filter compartment.

3. Using the shop vac, remove the water starting with the jets at the top and moving to the ones at the bottom of the spa.NOTE: When removing the water from the jet openings, you may notice suction coming from another jet. With the help of a second person, block off any suction from the other jet using a large rag or cloth. This will help pull out the water that is trapped deep inside the main line.

4. Thoroughly dry the spa shell with a clean towel.5. Using a funnel, pour Propylene glycol anti-freeze into the filter suction fittingsand jet outlets. Add enough anti-freeze until the liquid starts to

come out of the bottom drain.CAUTION: Use only Propylene glycol as your anti-freeze.This is non-

toxic. NEVER use automobile anti-freeze since it is toxic.

6. Close the spa cover and fasten the cover tie downs. If your area receives a lot of snow or ice, it is recommended to cover the spa cover with two pieces of plywood forming a pitched roof top to prevent snow and ice build-up. Secure a plastic sheet or tarp over the spa cover and one over the plywood.WARNING: When not in use, the spa must be covered with an insulating spa cover. Damage caused by either sun exposure or freezing is not covered under warranty.

7. In the pump side of the equipment control bay, remove the pump drain plug located on the front of the pump housings. Allow all water to drain out. Place the drain plug in a reclosable plastic storage bag and store near the pump. Replace the drain plugs on start-up.

8. Unscrew the suction/discharge pump and heater unions and allow the water to drain. Leave union loose. NOTE: Tighten unions before filling.9. Replace the equipment doors and secure with screws.

Service Information

SERVICE INFORMATIONGENERAL INFORMATIONYour Hot Spot® Spa has been designed to provide years of trouble-free use. As with any appliance, problems may occasionally occur that requirethe expertise of a qualified service person. Though such simple repairs as resetting a GFCI switch or breaker, high limit thermostat, or pressureswitch, or replacing a light bulb may not require a service call, they may indicate that a more serious condition exists. These conditions mayrequire an experienced service person. Before calling for service, please refer to the Troubleshooting Guide.NOTE: Always retain your original sales receipt for future reference.

GFCI AND HIGH-LIMIT THERMOSTATIf your spa fails to operate at any time, the following items should be checked:1. Check the power supply to the spa.2. Check the GFCI (located at the end of the cord in standard models or in the electrical subpanel in 30 amp converted models) and see if it has

tripped. If a GFCI has tripped, reset it. If it will not reset, this may be an indication of a ground fault (short circuit) within the electricalcomponents. Contact an Authorized Service Technician for a complete diagnosis.

3. If, upon checking the GFCI you find it has not tripped, check the house breaker panel and ensure the main breaker for the electrical circuitsupplying the spa has not tripped. If it has, this is an indication that either the circuit was overloaded or a ground fault exists between thebreaker panel and the spa receptacle. Contact a qualified electrician.

4. If, upon checking the main house breaker, you find no failures, the heater high-limit thermostat should be checked. Tripping of the heater high-limit thermostat is normally a result of one or a combination of any of these problems: 1) blockage within the system plumbing, 2) switchmalfunction in the heater circuit, or 3) the low speed mode of the jet pump is not functioning.

5. If the heater high-limit has tripped, the control panel display will display - - - - . Reset the heater high-limit by allowing the water to cool anddisconnecting power to the spa for at least thirty seconds. If the heater high-limit continues to trip, contact an Authorized Service Technicianfor a complete diagnosis.

If the spa does not function and the GFCI or GFCI breaker and heater high-limit have not tripped, then the problem should be referred to anAuthorized Service Technician. Refer to the Troubleshooting Guide for additional service information.

MISCELLANEOUS SERVICE INFORMATIONThe jet pump is equipped with an overload cut-off switch, which is designed to protect the pump from overheating. If the pump shuts itself off in anew spa, it is usually the result of one, or a combination of, the following factors:High Temperature: During the summer months, especially in warmer climates, the ambient temperature contributes to excessively hightemperatures within the equipment compartment.Improper House Wiring: If the spa is not connected to a dedicated circuit, or is connected to an extension cord, or the house wiring isundersized, the pump may starve for voltage and therefore may draw more amperage and generate excessive heat. This will often cause thecircuit breaker to trip repeatedly.

IMPORTANT:1. If the pump is shutting down due to excessive heat, make sure the equipment compartment has adequate ventilation. The air gap at the

bottom and the jet pump vent at the bottom left corner must not be blocked. Should your jet pump continue to shut off after short periods ofuse, contact a qualified service technician.

2. The Hot Spot® Spa is equipped with a safety suction spring valve which will break the prime of the jet pump if both suction fittings areobstructed.

ACTS INVALIDATING WARRANTYThe limited warranty is void if the Hot Spot Spa has been subjected to alteration, misuse or abuse, or if any repairs on the spa are attempted byanyone other than an authorized representative of Watkins Manufacturing Corporation.
